I have an itchy, tender, small growth in my hand. What could it be?

Hello,

Welcome to icliniq.com.

There are two diagnoses, which matches with your pictures (attachment removed to protect patient identity) and symptoms. The first one is infected nevus sebaceous and the second one is infected wart. Now let us differentiate the two diseases. Nevus sebaceous is a type of birthmark, which may be remain unnoticed. Now, it is infected and so become tender and symptomatic. Wart is a viral infection. Sometimes, it grows on the scalp like this. Due to touching, it becomes infected and tender. The treatment plan is as follows. First, I suggest an antibiotic cream like Mupricon cream on it for seven days to reduce the infection.

Then, I suggest oral antibiotics like Augmentin 625 mg (combination of Amoxicillin and Clavulanate) twice in a day for seven days. It will becomes dry and non tender once infection subsided. Consult your specialist doctor, discuss with him or her and take the medicine with their consent. Once it become dry and non-tender, go for removal of the lesion. In both cases, either wart or nevus, you have to get it removed by radiofrequency or surgically.
